species will stand as Chrostosoma fenestrina, Butl.

Draudt, M. (1915). Chrostosoma. In: Seitz, A. (ed.), The Macrolepidoptera
of the World, vol. 6, The American Bombyces and Sphinges: p. 67, pl. 12 k
(decisa); Additions and Corrections p. 200.

Ch. decisa Wkr. (12 k) has like the following a black-brown body,
carmine-red spots on the shoulder-covers and on the middle of the first
abdominal ring; metallic blue lateral spots; the underside is white; in
contrast with the following species, the vertex and metathorax are
spotted with metallic-blue, and the brown marginal band of the whitish
hindwings sends forth a long continuation towards the base below the cell.
Amazon, Bolivia.

Ch. haematica Perty (= zantes H.-Schaff., fenestrina Btlr., chalconitis
Druce) greatly resembles the preceding, but on the vertex the blue colour
is absent, the wings are in the basal part more smoky hyaline and on the
hindwings the continuation of the marginal band towards the base is
shorter. From Ecuador and Brazil.

Additions and corrections: P. 67, line 27 from below, for haematica insert
the name: Ch. fenestrina Btlr., haematica and zantes are to be eliminated,
there only remains the synonym chalconitis.
